Msport is simply a cosmetic pkg for those who want their 3 to look different from other 3's.

This is not the case for Canadian purchasers. The 335i M Sport option here offers the potential to add M Sport Adaptive suspension (not available with other lines), M Sport brakes (with Brembo callipers front and rear and larger rotors), and staggered 18" summer performance tires on M Sport alloys (only all seasons available with lines) in addition to the upgraded styling features.
